We loved hosting you at the REI Nation offices in Memphis, Bruce.

so if you just buy a random property with 100% financing, you'll never pay back the loans with the property - you'll be negative and  have to pay it back with other money.and if you BRRRR using 100% borrowed money you have to really knock it out of the park to get all your money back, which is very difficult to do as a new investor.the way BRRRR works (as you know) is you buy (with money - cash from your checking account, cash from your uncle, hard money, a HELOC, a cm) fix the property up, then refinance. 

However, they told me that I have to rezone my property as commercial and that I have to comply with a bunch of different regulations like updated landscaping, parking, etc.

I tried a lot of the free resources and most of the numbers are not working.Look up “National Cellular Directory”, they might have what you seek. 

There are no laws that I know of in this nation which says you have to provide AC in the first place let alone a specific temperature.

For example, if we're selling Paper Lots to a national builder, we would want to fit as many lots on the site as we can, because builders pay on a "per lot" basis. 

Plus covered garage parking and all utilities included. 

The approved contractors have to meet insurance guidelines (often not met by an average company), typically are certified by national and state agencies in home energy efficiency, and invest around $10k in energy testing equipment just to participate.

RV parks ( we would be new to this area of investing ).

I saw there are lots of roof-mount implementations on parking lots/high schools in CA recently.
